I The invention relates to means for preventing the floodingofbasements, cellars and analogous low places having connection with asewerage system when there is an abnormal rise of water, or increase inthe pressure from heavy rain, or a thaw in winter when the ground iscovered with snow and ice.

The invention consists of a check adapted to be located in the length ofthe soil pipecon- '10 necting with the sewer and comprising a frame, orcasing,"and a'fioat controlled valve which automatically closes upon anabnormal rise of water to prevent back flow and a flooding of thepremises.

While the drawing illustrates a preferred embodiment of the invention,it is to be understood that in adapting the means to meet specific needsand requirements, the design may be varied and changes in the minor de Iin tails of construction maybe resorted to within the scope of theinvention as claimed, without departing 1 from the spirit thereof.

For a full understandingof the invention and'the merits thereof,reference is to be 2 had to the, following description and the drawinghereto attached, in which Figure 1 is a central, longitudinal sectionalview illustrative of an embodiment of theinvention. l I H Figure 2 is atransverse.sectional'view .on the line 2-2 of Figure 1 looking in thedirection of the arrows. 7 Z

Figure 3 is a fragmentary sectional viewon theline 3'3 of Figure 2. I JFigure 4 is a sectional view similar to Figure '1 illustrating amodification and the addition of adj unctive parts whereby to vent theattachment and to draw off water from v the house end of the sewerand'discharg'e the same into the sewer end whenthe valve is closed byan'abnormal rise ofwater. Figure 5 is a horizontal sectional view on theline 55 of Figure 4. v Figure 6- is-an enlarged detail sectional view onthe line 66 of Figure 4.

Corresponding and like parts are referred to in the followingdescription and designated in the several views of the drawingbylikereference characters. V7

Thenumeral 1 denotes the usual soil pipe which connects the premises tobe drained with the sewer. In accordance with the present invention thecheck is located in; the length of the pipe 1 and comprises a framecreasing and afloat controlled valve. When the check is constructed 'tobe installed in sewers in service the frame or casing is constructedsubstantially as shown to be clamped again'sta side'of the pipe 1, butwhen constructed to be applied to new sewers the frame or casing will beof such formation as to be set into the length of the soil pipe withoutnecessitating thebreaking away or removalof the side portion of the pipefor the installation of'thecheck." I

V In the present instance the frame or casing comprises a body 2*and acover 3 which is bolted or otherwise secured to the body to close thetop thereof and admit of ready access thereto for any desired purpose.The

bottom of the body 2 is open to admit of communication being establishedbetween the sewer pipe 1 and the interior "of the frame or casing.Thelbottom edge of opposite end walls of the frame is depressed orcurved to conform to the curvature of the sewer pipe 1 to fit the sameclosely. The bottom edge of the side walls of the frame is'bevelled fora like purpose, as indicated most clearly in Figure 2 of the drawing.

' Flanges 4 project outwardly from the end walls of the frame or casingand curve transversely to conform to the curvature of the pipe 1..Cement 5 or other suitable material is interposed between the flanges 4and the adjacent side of the pipe 1 to insure the formation of atightjoint. Lugs 6 project laterally from the sides of the frame orcasin and receive thev threaded ends of straps F which extend beneaththe pipe and have nuts 8 threaded upon the projecting ends to clamp theframe to the top side'of the pipe'l.

A gate valve 9 is snugly fitted against the inner sidev of an end wallof the frame or casing and its'lowerf portion is curved to conform tothe inner diameter of'the sewer pipe '1. GuideslO applied totheinnerside of the end wall engage verticaledge portions of the gate valve9 andhold it in place and give direction thereto in its verticalmovements.

A lever 11 pivotally mounted intermediate its normal conditions tendingto create a backflow in the sewer and the flooding of the premises, thefloat 13 rises and the gate valve.

9 is lowered, thereby cutting off the fiowto the sewer andpreventingback flow and a consequent flooding.

Lugs 1.4 1 project inwardly from the side walls of theframe orcasing andare formed with vertical openings to receive the guide members ofasubstantiallyUYsh-aped hanger 15 upon which the lever .11 is pivotallymounted. Clampscrews16threaded into the lugs 14 secure theIU-shapedhanger 15 int-he required adjusted position. To install the form ofcheck shown in the accompanying drawing in an existing sewer it isnecessary to remove aportionfrom thetop side of the pipe 1 toaccommodate the frame-creasing and the valve 9 and-float 13. When thedevice isproperly positioneditis-made secure by means of the straps 7,.lnstallationland adjustment of thegparts may be facilitated'by removingthe cover' 3. After the parts have been;properly-adjusted andthe frameor casing made s'ecureithe cover .3-isireplaced. Ad-- justment'v-of thehanger 15 facilitates posi tioni ng of-the valveand floatto securesatisfactory results,

The numeral 17 dcnotes'a centrifugal pump which isarrangedxtoidraw waterfrom the hou'seend of thesewer anddischarge .itlinto the sewer-endbeyond the valve 9. Asuc tion pipe 18 isconnected with thecasing of thepump 17 :and a disch-arge p-ipe 19 connects the outlet of the pump 17with the frame or casing 2 of the attachment. i-Ashortpipe or nipple '20is fitted in an opening Lformed in-a sideofthelframe orcasingQ."Thedischarge pipe 19 is connected to the nipple or pipe-20. V

A headQlisiformed at oneendofthe pipe cr;nipple:20and engages the innerside of the frame-or 'casing2. Arnut-l2'2 threaded upon the projectingend of the nipple or, pipe 20- serves to clamp :a wall of the casingf2be tween it and the head-:21; as shown mostelearlyin Figure 6ofthedrawings. Tlhe face of the head: 21 is-incl'ined. and .providesa seatfor a valve 23 which-is \pivotedr at its upper end to tho head .21.3Theiface0f theheadQl forming the .seat foiwthe valvel2'3 is inclined toinsure a positive closing of the valve. A packing 24. isinterposedbetweem the head 1 andthe wallofthecasingor frame 2 to insure.aclose joint and prevent anyleak,

1 Abrackete25 supports thepump 1 7 and is secured to the flange 4 at oneend of the frame or casing 2. An upright 26 is secured at its lower endto the frame or casing 2 and receives an electric motor 27 which isconnected by means of a shaft 28 to the rotor of the pump 17. Thecircuit supplying current to the motor 27 isadapted .tohe closedby meansof a switch-29 which is operable tbymeans of the float 13 when the waterrises in the sewer to a point to effect a closing of the valve 9. A vent30is provided in the top or cover 3 and consists of a body having apassage formed therein, the lower end of the passage opening throughaside of the body and adaptt ed to be closed when the said body iselevated to thelimit of itsupward movement.v .Acrod 31:formsconnectingmeans between-the vent 30'and the movable member of the:switch- 29. An upright-32 attached "to'the top or'cover 3 supportstheswitch 29.

WVhen thereis'an abnorm-alrise of water in the sewer andthe'valve.91-is'closedthe premises are prevented from fioodinglbyreofwater disc'harging into the house-end of the sewer:by means'of-the pump-17 which draws water from the house end of the sewer and discharges thesame into theendportionrconnected with the sewereand beyond the valve 9.WVhen the water riseszthe float -13'also risesand liftingthe vent30-,elosesthe switch 29 whereby'th'e motor.27lisenergized andlthe pump17 operated. Thevent 30 provides an escape for air --when the water:risesiinxthe sewer. When the wateris at-itshighest vpoint thevalve 9 isclosed .andithe-pump .17 operates to .drawthe water from-thehouseisideand discharge it into the sewersidesof the soil pipe therebypreventingflooding of the premises fromroo'f water/and other discharge into thesewer. Whenthe water subsides the float 13 descends and'permits of theventlowering and'the circuitto the motorbeingcautomatically broken. Thepump therefore "is automatic inaction, both in the. starting: andstopping. a
